I've been in US on F1 visa since August of 2015. This is the first tax-filing year that I'm eligible for substantial presence test, which says I should file the resident tax form 1040. However I don't know which of the stimulus checks ($1200,$600 and $1400) I'm qualified for. In particular, turbo tax asks me which of the past stimulus checks ($1200, $600) I have received. I have received neither, but I'm not sure if it's because I was not qualified or because I had not filed any 1040 form before.
Which option should I choose in the turbo tax regarding the stimulus question?
